	 * 通用导出Excel文件方法
	 * 利用了JAVA的反射机制，可以将放置在JAVA集合中并且符合一定条件的数据以EXCEL 的形式输出到指定IO设备上
	 * @param title 表格标题名
	 * @param headers 表格属性列名数组
	 * @param dataset 需要显示的数据集合,集合中一定要放置符合javabean风格的类的对象。此方法支持的
	 *            	  javabean属性的数据类型有基本数据类型及String,Date,byte[](图片数据)
	 * @param out 与输出设备关联的流对象，可以将EXCEL文档导出到本地文件或者网络中
	 * @param pattern  如果有时间数据，设定输出格式。默认为"yyy-MM-dd"
